No. 15/924,815, filed Mar. 19, 2018, which is a continuation of International Application No. PCT/JP2016/068553 filed on Jun. 22, 2016, and claims priority under 35 U.S.C. § 119(a) to Japanese Patent Application No. 2015-194236 filed on Sep. 30, 2015, the entire disclosures of which are incorporated herein by reference in their entirety.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to an imaging apparatus.

2. Description of the Related Art

As imaging apparatuses in which a live view image is displayed on a display disposed along one surface of a main body having an imaging element, there are known imaging apparatuses which are provided with a movable display, and are configured to be capable of imaging at various imaging angles of a high angle and a low angle without changing an imaging posture.

As shown in FIGS. 31, 32A and 32B, a digital camera disclosed in JP5461738B includes a hinge unit 3 that movably connects a display 2 disposed along one surface of a main body 1 to the main body 1.

The hinge unit 3 is connected to the main body 1 so as to be rotationally movable about an axis A by a pair of first hinges 4 having a shaft member, not shown, inserted into a bearing hole 4 a which is provided to each of the main body 1 and the hinge unit 3. The display 2 is supported by the hinge unit 3 so as to be rotationally movable about an axis B which is at right angles to the axis A by a pair of second hinges 5 having a shaft portion 5 b, provided to the display 2, inserted into a bearing hole 5 a provided in the hinge unit 3.

For example, the display 2 is rotationally moved about the axis A integrally with the hinge unit 3 in a horizontal structure in which an imaging range extends in a relatively horizontal direction, and the display 2 is independently rotationally moved about the axis B in a vertical structure in which an imaging range extends in a relatively vertical direction. In the case of both the horizontal structure and the vertical structure, the angle of the display 2 can be changed in accordance with an imaging angle.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1A and 1B are an example of an imaging apparatus according to an embodiment of the present invention.

A digital camera 10 as the imaging apparatus shown in FIGS. 1A and 1B includes a main body 12 having an imaging element 11 such as a charge coupled device (CCD) image sensor or a complementary metal oxide semiconductor (CMOS) image sensor, a display 13, and a hinge unit that movably connects the display 13 to the main body 12.

The display 13 includes a display panel 15 such as a liquid crystal or organic EL, and a cover 16 having a window for exposing the display region of the display panel 15 formed thereon, and is formed in a substantially rectangular shape when the display panel 15 is seen from the front. The rear surface of the main body 12 is provided with a concave portion 17 formed in a substantially rectangular shape similarly to the display 13, and the display 13 is received in the concave portion 17 and is disposed along the rear surface of the main body 12.

The concave portion 17 is open to the bottom of the main body 12 and one lateral side of the main body 12. The lateral side of one long side 13 a and the lateral side of one short side 13 b among four lateral sides of the display 13 are exposed in a state where the display 13 is received in the concave portion 17.

As shown in FIGS. 2A and 2B, the hinge unit of the present example connects the display 13 to the main body 12 so as to be rotationally movable about an axis A (first axis) extending along the long side 13 a of the display 13, and to be rotationally movable about an axis B (second axis) which is substantially at right angles to the axis A and extends along a short side 13 d of the display 13. Meanwhile, the meaning that the axis A and the axis B extend “along” the sides of the display 13 refers to the meaning that the axis A and the axis B are parallel to the sides of the display 13 without being away from the sides.

FIG. 3 shows a configuration of the hinge unit of the digital camera 10.

A hinge unit 14 includes a fixed portion 20 which is fixed to the bottom of the concave portion 17 of the main body 12, and a support portion 21 that supports the display 13.

The fixed portion 20 is provided with a pair of hinge brackets 30 which are disposed on the axis A, and the support portion 21 is provided with a pair of hinge brackets 31 which are superimposed on the hinge brackets 30 in the axial direction of the axis A. The hinge bracket 30 and the hinge bracket 31 superimposed on each other are coupled to each other by a hinge pin 32 so as to be rotatable relative to each other.

A first hinge 23 which is disposed on the axis A is constituted the hinge bracket 30, the hinge bracket 31 and the hinge pin 32. The support portion 21 is connected to the main body 12 through the fixed portion 20 so as to be rotationally movable about the axis A by a pair of first hinges 23 on the axis A.

The support portion 21 is provided with a pair of hinge brackets 33 which are disposed on the axis B, and the display 13 is provided with a pair of hinge brackets 34 which are superimposed on the hinge brackets 33 in the axial direction of the axis B. The hinge bracket 33 and the hinge bracket 34 superimposed on each other are coupled by a hinge pin 35 so as to be rotatable relative to each other.

A second hinge 24 which is disposed on the axis B is constituted by the hinge bracket 33, the hinge bracket 34 and the hinge pin 35. The display 13 is supported by the support portion 21 so as to be rotationally movable about the axis B by a pair of second hinges 24 on the axis B.

According to the hinge unit 14, the display 13 is rotationally moved about the axis A integrally with the support portion 21 of the hinge unit 14, and is independently rotationally moved about the axis B.

The pair of first hinges 23 on the axis A are disposed on both ends of the long side 13 a of the display 13, respectively, along which the axis A extends, and have an improvement in further stability of the rotational movement of the display 13 about the axis A than in a case where the pair of first hinges 23 are disposed adjacent to each other.

Similarly, the pair of second hinges 24 on the axis B are disposed on both ends of the short side 13 d of the display 13, respectively, along which the axis B extends, and have an improvement in further stability of the rotational movement of the display 13 about the axis B than in a case where the pair of second hinges 24 are disposed adjacent to each other.

In a state where the display 13 is received in the concave portion 17 and is disposed along the rear surface of the main body 12, the hinge unit 14 is covered with the cover 16 of the display 13, and is not exposed to the outward appearance of the digital camera 10. The hinge unit 14 is not exposed to the outward appearance of the digital camera 10, and thus it is possible to improve the design of the digital camera 10.

FIG. 4A schematically shows the disposition of the pair of first hinges 23 and the pair of second hinges 24 of the hinge unit 14, and FIG. 4B schematically shows a trajectory of the hinge unit 14 when the hinge unit 14 is rotationally moved about the axis B of the pair of second hinges 24.

As shown in FIGS. 4A and 4B, in the hinge unit 14 of the present example, one first hinge 23 of the pair of first hinges 23 on the axis A which is located closer to the axis B is disposed between the pair of second hinges 24 on the axis B. In the drawings, the frame of a dashed-two dotted line shows the outer circumference of the cover 16 when the display panel 15 of the display 13 is seen from the front.

FIGS. 5A, 5B, 6A, 6B, 7A and 7B show a case where the first hinge 23 located closer to the axis B is disposed away from between the pair of second hinges 24.

FIGS. 5A and 5B show a case where the first hinge 23 located closer to the axis B is disposed away from between the pair of second hinges 24 in the axial direction of the axis B, and the axis A and the axis B intersect each other on the outer side of the pair of second hinges 24. In this case, the outer circumferences of the hinge unit 14 and the cover 16 that covers the hinge unit 14 are extended, as cross-hatched in the drawings, in the axial direction of the axis B with respect to the outer circumferences of the hinge unit 14 and the cover 16 shown in FIGS. 4A and 4B.

FIGS. 6A and 6B show a case where the first hinge 23 located closer to the axis B is disposed away from between the pair of second hinges 24 in the axial direction of the axis A, and the axis A and the axis B intersect each other on the outer side of the pair of first hinges 23, that is, the pair of first hinges 23 are disposed on one side of the axis B in the axial direction of the axis A. In this case, the outer circumferences of the hinge unit 14 and the cover 16 that covers the hinge unit 14 are extended, as cross-hatched in the drawings, in the axial direction of the axis A with respect to the outer circumferences of the hinge unit 14 and the cover 16 shown in FIGS. 4A and 4B.

FIGS. 7A and 7B show a case where the first hinge 23 located closer to the axis B is disposed away from between the pair of second hinges 24 in the axial direction of the axis A, and the axis A and the axis B intersect each other between the pair of first hinges 23, that is, one first hinge 23 located closer to the axis B is disposed on the opposite side to the other first hinge 23 with the axis B interposed therebetween. In this case, the outer circumference of the cover 16 that covers the hinge unit 14 is equivalent to the outer circumference of the cover 16 shown in FIGS. 4A and 4B.

However, one first hinge 23 located closer to the axis B is disposed on the opposite side to the other first hinge 23 with the axis B interposed therebetween, and thus the first hinge 23 located closer to the axis B is revolved about the axis B toward the bottom of the concave portion 17 of the main body 12, in association with the rotational movement of the display 13 about the axis B. The first hinge 23 located closer to the axis B is disposed away from between the pair of second hinges 24 in the axial direction of the axis A and thus leads to an increase in revolution radius. For this reason, the bottom of the concave portion 17 of the main body 12 is required to have a clearance groove for avoiding interference with the first hinge 23.

In this manner, one first hinge 23 of the pair of first hinges 23 which is located closer to the axis B is disposed between the pair of second hinges 24, and thus it is possible to reduce the size of the hinge unit 14.

Next, description will be given of various modification examples of the digital camera 10 having an improvement in the rotational movement operability of the display 13 which is rotationally moved about the axis A integrally with the support portion 21 of the hinge unit 14 and is independently rotationally moved about the axis B.

In examples shown in FIGS. 8, 9A and 9B, a first rotational movement operating portion 40 and a second rotational movement operating portion 41 are included.

The first rotational movement operating portion 40 is provided to the support portion 21 of the hinge unit 14, and is disposed away from the axis A on a long side 13 c located opposite to the long side 13 a of the display 13 along which the axis A extends. The first rotational movement operating portion 40 is provided so as to be exposed to the outer circumference of the display 13 in a state where a portion of the cover 16 of the display 13 that covers the hinge unit 14 is cut out, and is constituted by a small piece-shaped protrusion capable of having a finger hooked thereon.

The second rotational movement operating portion 41 is provided to the display 13, and is disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends. The second rotational movement operating portion 41 is also constituted by a small piece-shaped protrusion capable of having a finger hooked thereon.

In a case where the first rotational movement operating portion 40 is lifted up, the support portion 21 of the hinge unit 14 provided with the first rotational movement operating portion 40 is rotationally moved about the axis A, and the display 13 supported by the support portion 21 is also rotationally moved about the axis A integrally with the support portion 21. In a case where the second rotational movement operating portion 41 is lifted up, the display 13 provided with the second rotational movement operating portion 41 is independently rotationally moved about the axis B. Thereby, the display 13 is prevented from being erroneously operated in its rotational movement about each of the axis A and the axis B, and thus it is possible to improve the rotational movement operability of the display 13.

In the example shown in FIG. 8, FIGS. 9A and 9B, individual rotational movement operating portions are provided for the rotational movement of the display 13 about the axis A and the rotational movement of the display about the axis B, respectively, but examples shown in FIGS. 10, 11A and 11B show one rotational movement operating portion 50 which is simplified.

The rotational movement operating portion 50 is provided to the display 13, and is disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends.

The rotational movement operating portion 50 includes an engagement member 51 and a biasing member 52. The engagement member 51 is supported by the cover 16 of the display 13 so as to be movable between a locked position P1 engaged with the support portion 21 of the hinge unit 14 and an unlocked position P2 released from engagement with the support portion 21. The direction of movement from the locked position P1 of the engagement member 51 to the unlocked position P2 may be parallel to the axial direction of the axis A, and may be parallel to the axial direction of the axis B, which has no particular limitation thereon. The biasing member 52 biases the engagement member 51 toward the locked position P1.

The engagement member 51 is provided with a small piece-shaped protruding portion 53 which is exposed to the outer circumference of the display 13, and is capable of having a finger hooked thereon. By the operation of the protruding portion 53, the rotational movement operating portion 50 is lifted up, and the engagement member 51 is moved from the locked position P1 to the unlocked position P2.

In a case where the engagement member 51 is engaged with the support portion 21 of the hinge unit 14 at the locked position P1, the display 13 is integrated with the support portion 21. Since the support portion 21 is not rotatable about the axis B with respect to the main body 12, the display 13 is rotatable only about the axis A in a state where the engagement member 51 is engaged with the support portion 21. The lateral side of one short side 13 b of the display 13 is exposed by the concave portion 17 which is open to one lateral side of the main body 12. For example, in a state where a finger is hooked on the exposed lateral side of the short side 13 b, the lateral side of the short side 13 b is lifted up, and the display 13 is rotationally moved about the axis A.

In a state where the engagement member 51 is moved to the unlocked position P2 and is released from engagement with the support portion 21, the display 13 is also rotatable about the axis B. In a case where the rotational movement operating portion 50 is lifted up in this state, the display 13 provided with the rotational movement operating portion 50 is independently rotationally moved about the axis B. Thereby, the display 13 is prevented from being erroneously operated in its rotational movement about each of the axis A and the axis B, and thus it is possible to improve the rotational movement operability of the display 13.

In each of examples shown in FIGS. 12, 13, 14A and 14B, the initial torque of rotational movement of the display 13 about the axis B is made larger than the initial torque of rotational movement of the display 13 about the axis A. Meanwhile, the initial torque of rotational movement of the display 13 about each of the axis A and the axis B refers to a torque required during initial movement when the display 13 disposed along the rear surface of the main body 12 is rotationally moved in the direction of separating from the rear surface of the main body 12.

In addition, the lateral side of one short side 13 b of the display 13 is exposed by the concave portion 17 which is open to one lateral side of the main body 12. In the present example, in a state where a finger is hooked on the exposed lateral side of the short side 13 b, the lateral side of the short side 13 b is lifted up, and the display 13 is rotationally moved in the direction of separating from the rear surface of the main body 12.

The revolution radius of an operation region about the axis B on the lateral side of the short side 13 b becomes longer than the revolution radius thereof about the axis A. Consequently, the initial torque of rotational movement of the display 13 about the axis B is made relatively large, and thus an operation load during the rotational movement of the display 13 about the axis B can be made substantially equal to an operation load during the rotational movement of the display about the axis A, or can be made larger than an operation load during the rotational movement of the display about the axis A. Thereby, the display 13 is prevented from being carelessly rotationally moved about the axis B, and thus it is possible to improve the rotational movement operability of the display 13.

In an example shown in FIG. 12, a pair of magnets are included.

One magnet 60 is provided to the support portion 21 of the hinge unit 14, and the other magnet 61 is provided to the display 13. The magnet 60 and the magnet 61 are disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends, and are disposed so that magnetic poles different from each other face each other.

The display 13 is adsorptively fixed to the support portion 21 due to an attractive force which is generated between the magnet 60 and the magnet 61. Since the magnet 60 and the magnet 61 are disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends, the initial torque of rotational movement of the display 13 about the axis B is increased due to the attractive force between magnet 60 and the magnet 61. A torque about the axis B based on the attractive force between the magnet 60 and the magnet 61 is appropriately adjusted depending on surface magnetic flux density and facing interval between the magnet 60 and the magnet 61, and a distance between the magnets 60 and 61 and the axis B, and the initial torque of rotational movement of the display 13 about the axis B is set to be larger than the initial torque of rotational movement of the display about the axis A.

Preferably, the magnet 60 and the magnet 61 are provided adjacent to the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends so that the attractive force between the magnet 60 and the magnet 61 effectively acts as a torque about the axis B.

Further, when the display 13 rotationally moved about the axis B in the direction of separating from the rear surface of the main body 12 is rotationally moved again in a direction along the rear surface of the main body 12, the attractive force between the magnet 60 and the magnet 61 also acts so as to attract the display 13 to the rear surface of the main body 12. The display 13 rotationally moved up to the vicinity of the rear surface of the main body 12 is attracted to the rear surface of the main body 12 due to the attractive force between the magnet 60 and the magnet 61, and is automatically disposed at a proper position along the rear surface of the main body 12. Thereby, it is possible to further improve the rotational movement operability of the display 13.

Meanwhile, as shown in FIG. 13, when the main body 12 is provided with a magnet 62, and the display 13 rotationally moved about the axis A in the direction of separating from the rear surface of the main body 12 is rotationally moved again in a direction along the rear surface of the main body 12 due to an attractive force which is generated between the magnet 62 provided to the support portion 21 of the hinge unit 14 and the magnet 60, the display 13 may be attracted to the rear surface of the main body 12. In this case, from the viewpoint that the initial torque of rotational movement of the display 13 about the axis B is made relatively large, the attractive force between the magnet 60 and the magnet 62 is set to be smaller than the attractive force between magnet 60 and the magnet 61, and thus, for example, the surface magnetic flux density of the magnet 62 becomes smaller than the surface magnetic flux density of the magnet 61, or the facing interval between the magnet 60 and magnet 62 becomes larger than the facing interval between the magnet 60 and the magnet 61.

The attraction of the display 13 to the rear surface of the main body 12 can also be performed by a click mechanism giving a click feeling to the rotational movement operation of the display 13, and the initial torque of rotational movement of the display 13 about the axis B can also be made relatively large using this click mechanism.

In the example shown in FIGS. 14A and 14B, the first hinge 23 and the second hinge 24 are each provided with a click mechanism.

The click mechanism of the first hinge 23 includes a sliding contact plate 70, provided adjacent to the hinge bracket 31 of the support portion 21 constituting the first hinge 23, which is fixed to the hinge pin 32. The hinge bracket 31 is provided with a convex portion 71, and the sliding contact plate 70 is provided with a concave portion 72. The convex portion 71 and the concave portion 72 are engaged with each other in a state where the display 13 is disposed along the rear surface of the main body 12. Meanwhile, the hinge bracket 31 may be provided with a concave portion, and the sliding contact plate 70 may be provided with a convex portion.

In a case where the display 13 disposed along the rear surface of the main body 12 is rotationally moved about the axis A in the direction of separating from the rear surface of the main body 12, the support portion 21 is also rotationally moved integrally with the display 13, the hinge bracket 31 and the sliding contact plate 70 are rotationally moved relative to each other, and the engagement of the convex portion 71 with the concave portion 72 is released. In a case where the display 13 is rotationally moved again in a direction along the rear surface of the main body 12, the convex portion 71 and the concave portion 72 are engaged with each other, the display 13 is attracted to the rear surface of the main body 12 in the process of the engagement of the convex portion 71 with the concave portion 72, and a click feeling is generated at a timing when the engagement of the convex portion 71 with the concave portion 72 is completed.

The click mechanism of the second hinge 24 includes a sliding contact plate 73, provided adjacent to the hinge bracket 34 of the display 13 constituting the second hinge 24, which is fixed to the hinge pin 35. The hinge bracket 34 is provided with a convex portion 74, and the sliding contact plate 73 is provided with a concave portion 75. The convex portion 74 and the concave portion 75 are engaged with each other in a state where the display 13 is disposed along the rear surface of the main body 12. Meanwhile, the hinge bracket 34 may be provided with a concave portion, and the sliding contact plate 73 may be provided with a convex portion.

In a case where the display 13 disposed along the rear surface of the main body 12 is rotationally moved about the axis B in the direction of separating from the rear surface of the main body 12, the hinge bracket 34 and the sliding contact plate 73 are rotationally moved relative to each other, and the engagement of the convex portion 74 with the concave portion 75 is released in association with the elastic bending of the sliding contact plate 73. In a case where the display 13 is rotationally moved again in a direction along the rear surface of the main body 12, the convex portion 74 and the concave portion 75 are engaged with each other, the display 13 is attracted to the rear surface of the main body 12 in the process of the engagement of the convex portion 74 with the concave portion 75, and a click feeling is generated at a timing when the engagement of the convex portion 74 with the concave portion 75 is completed.

In the click mechanism of the first hinge 23 described above, the sliding contact plate 70 is elastically bent when the engagement of the convex portion 71 with the concave portion 72 is released, and a force required for the deformation of the sliding contact plate 70 is set to the initial torque of rotational movement of the display 13 about the axis A. Similarly, in the click mechanism of the second hinge 24, the sliding contact plate 73 is elastically bent when the engagement of the convex portion 74 with the concave portion 75 is released, and a force required for the deformation of the sliding contact plate 73 is set to the initial torque of rotational movement of the display 13 about the axis B.

Consequently, for example, an engagement margin H2 between the convex portion 74 and the concave portion 75 of the click mechanism of the second hinge 24 is made larger than an engagement margin H1 between the convex portion 71 and the concave portion 72 of the click mechanism of the first hinge 23, and thus the initial torque of rotational movement of the display 13 about the axis B can be made relatively large. In addition, a thickness T2 of the sliding contact plate 73 of the click mechanism of the second hinge 24 is made larger than a thickness T1 of the sliding contact plate 70 of the click mechanism of the first hinge 23, and thus the initial torque of rotational movement of the display 13 about the axis B can also be made relatively large.

Examples shown in FIGS. 15, 16A and 16B show that, in a case where the display 13 is rotationally moved about the axis B, the display 13 is prevented from being rotationally moved about the axis A.

The concave portion 17 of the main body 12 having the display 13 received therein is provided with an engagement member 80 and a biasing member 81. The engagement member 80 is disposed on a revolution trajectory about the axis B of an edge E of the cover 16 constituting the lateral side of the short side 13 d of the display 13 along which the axis B extends, and is pressed by the edge E of the cover 16 when the display 13 disposed along the rear surface of the main body 12 is rotationally moved about the axis B in the direction of separating from the rear surface of the main body 12.

The engagement member 80 is supported by the main body 12 so as to be movable in a pressing direction between the locked position P1 at which the support portion 21 is fixed to the main body 12 by engagement with the support portion 21 of the hinge unit 14 and the unlocked position P2 released from the engagement with the support portion 21. The biasing member 81 biases the engagement member 80 toward the unlocked position P2.

In a state where the engagement member 80 is released from the engagement with support portion 21 of the hinge unit 14 at the unlocked position P2, the display 13 is rotatable about each of the axis A and the axis B. The lateral side of one short side 13 b of the display 13 is exposed by the concave portion 17 which is open to one lateral side of the main body 12. For example, the lateral side of the short side 13 b is lifted up in a state where a finger is hooked on the exposed lateral side of the short side 13 b, and the display 13 is rotationally moved about the axis A or the axis B.

In a case where the display 13 is rotationally moved about the axis B, the engagement member 80 is moved to the locked position P1 due to pressure by the edge E of the cover 16 of the display 13, and engages with the support portion 21 of the hinge unit 14. The support portion 21 is fixed to the main body 12 by the engagement of the engagement member 80 with the support portion 21, the support portion 21 is prevented from being rotationally moved about the axis A, and the display 13 is also prevented from being rotationally moved about the axis A.

In this manner, in a case where the display 13 is rotationally moved about the axis B, the unnecessary rotational movement of the display 13 is eliminated by preventing the display 13 from being rotationally moved about the axis A, and thus it is possible to improve the rotational movement operability of the display 13.

FIGS. 17A to 17C show another example of an imaging apparatus according to an embodiment of the present invention. Meanwhile, common components with respect to those of the above-described digital camera 10 are denoted by common reference numerals and signs, and thus the description thereof will be omitted or simplified.

A digital camera 110 as an imaging apparatus shown in FIGS. 17A to 17C includes a main body 12 having an imaging element, a display 13, and a hinge unit. The hinge unit movably connects the display 13 to the main body 12. In the present example, the hinge unit connects the display 13 to the main body 12 so as to be rotationally movable about an axis A (first axis) extending along the long side 13 a of the display 13, to be rotationally movable about an axis B (third axis) which is substantially at right angles to the axis A and extends along the short side 13 d of the display 13, and to be rotationally movable about an axis C (second axis) parallel to the axis A which is biased toward the long side 13 c of the display 13 with respect to the axis A.

FIG. 18 shows a configuration of the hinge unit of the digital camera 110.

A hinge unit 114 includes a fixed portion 120 which is fixed to the bottom of the concave portion 17 of the main body 12, and a first support portion 121 and a second support portion 122 that support the display 13.

The fixed portion 120 is provided with a pair of hinge brackets 130 which are disposed on the axis A, and the first support portion 121 is provided with a pair of hinge brackets 131 which are superimposed on the hinge brackets 130 in the axial direction of the axis A. The hinge bracket 130 and the hinge bracket 131 which are superimposed on each other are coupled by a hinge pin 132 so as to be rotatable relative to each other.

A first hinge 123 disposed on the axis A is constituted by the hinge bracket 130, the hinge bracket 131 and the hinge pin 132. The first support portion 121 is connected to the main body 12 through the fixed portion 120 so as to be rotationally movable about the axis A by a pair of first hinges 123 on the axis A.

The first support portion 121 is provided with a pair of hinge brackets 133 which are disposed on the axis C, and the second support portion 122 is provided with a pair of hinge brackets 134 which are superimposed on the hinge brackets 133 in the axial direction of the axis C. The hinge bracket 133 and the hinge bracket 134 which are superimposed on each other are coupled by a hinge pin 135 so as to be rotatable relative to each other.

A second hinge 124 which is disposed on the axis C is constituted by the hinge bracket 133, the hinge bracket 134 and the hinge pin 135. The second support portion 122 is supported by the first support portion 121 so as to be rotationally movable about the axis C by a pair of second hinges 124 on the axis C.

The second support portion 122 is provided with a pair of hinge brackets 136 which are disposed on the axis B, and the display 13 is provided with a pair of hinge brackets 137 which are superimposed on the hinge brackets 136 in the axial direction of the axis B. The hinge bracket 136 and the hinge bracket 137 which are superimposed on each other are coupled by a hinge pin 138 so as to be rotatable relative to each other.

A third hinge 125 which is disposed on the axis B is constituted by the hinge bracket 136, the hinge bracket 137 and the hinge pin 138. The display 13 is supported by the second support portion 122 so as to be rotationally movable about the axis B by a pair of third hinges 125 on the axis B.

According to the hinge unit 114 described above, the display 13 is rotationally moved about the axis A integrally with the first support portion 121 and the second support portion 122 of the hinge unit 14, is rotationally moved about the axis C integrally with the second support portion 122, and is independently rotationally moved about the axis B.

In a state where the display 13 is received in the concave portion 17 and is disposed along the rear surface of the main body 12, the hinge unit 114 is covered with the cover 16 of the display 13, and is not exposed to the outward appearance of the digital camera 10. The hinge unit 114 is not exposed to the outward appearance of the digital camera 10, and thus it is possible to improve the design of the digital camera 10.

FIG. 19A schematically shows the disposition of the pair of first hinges 123, the pair of second hinges 124 and the pair of third hinges 125 of the hinge unit 114, and FIG. 19B schematically shows a trajectory of the hinge unit 114 when the hinge unit 114 is rotationally moved about the axis B of the pair of third hinges 125.

As shown in FIGS. 19A and 19B, in the hinge unit 114 of the present example, one first hinge 123 of the pair of first hinges 123 on the axis A which is located closer to the axis B and one second hinge 124 of the pair of second hinges 124 on the axis C which is located closer to the axis B are disposed between the pair of third hinges 125 on the axis B. In the drawings, the frame of a dashed-two dotted line shows the outer circumference of the cover 16 when the display panel 15 of the display 13 is seen from the front.

FIGS. 20A, 20B, 21A, 21B, 22A and 22B show a case where one first hinge 123 of the pair of first hinges 123 which is located closer to the axis B and one second hinge 124 of the pair of second hinges 124 which is located closer to the axis B are disposed away from between the pair of third hinges 125.

FIGS. 20A and 20B show a case where the first hinge 123 and the second hinge 124 which are located closer to the axis B are disposed away from between the pair of third hinges 125 in the axial direction of the axis B, and the axis A and the axis C, and the axis B intersect each other on the outer side of the pair of third hinges 125. In this case, the outer circumferences of the hinge unit 114 and the cover 16 that covers the hinge unit 114 are extended, as cross-hatched in the drawings, in the axial direction of the axis B with respect to the outer circumferences of the hinge unit 114 and the cover 16 shown in FIGS. 19A and 19B.

FIGS. 21A and 21B show a case where the first hinge 123 and the second hinge 124 which are located closer to the axis B are disposed away from between the pair of third hinges 125 in the axial direction of the axis A, the axis A and the axis B intersect each other on the outer side of the pair of first hinges 123, and the axis C and the axis B intersect each other on the outer side of the pair of second hinges 124. In this case, the outer circumferences of the hinge unit 114 and the cover 16 that covers the hinge unit 114 are extended, as cross-hatched in the drawings, in the axial direction of the axis A with respect to the outer circumferences of the hinge unit 114 and the cover 16 shown in FIGS. 19A and 19B.

FIGS. 22A and 22B show a case where the first hinge 123 and the second hinge 124 which are located closer to the axis B are disposed away from between the pair of third hinges 125 in the axial direction of the axis A, the axis A and the axis B intersect each other between the pair of first hinges 123, and the axis C and the axis B intersect each other between the pair of second hinges 124. In this case, the outer circumference of the cover 16 that covers the hinge unit 114 is equivalent to the outer circumference of the cover 16 shown in FIGS. 19A and 19B.

However, the first hinge 123 and the second hinge 124 which are located closer to the axis B are revolved about the axis B toward the bottom of the concave portion 17 of the main body 12 in association with the rotational movement of the display 13 about the axis B. The first hinge 123 and the second hinge 124 which are located closer to the axis B are disposed away from between the pair of third hinges 125 in the axial direction of the axis A and thus lead to an increase in revolution radius. For this reason, the bottom of the concave portion 17 of the main body 12 is required to have a clearance groove for avoiding interference with the first hinge 123 and the second hinge 124.

In this manner, one first hinge 123 of the pair of first hinges 123 which is located closer to the axis B and one second hinge 124 of the pair of second hinges 124 which is located closer to the axis B are disposed between the pair of third hinges 125, and thus it is possible to reduce the size of the hinge unit 114.

Meanwhile, a configuration has been described in which both the first hinge 123 and the second hinge 124 which are located closer to the axis B are disposed between the pair of third hinges 125, but in a case where at least one of the first hinge 123 or the second hinge 124 which is located closer to the axis B is disposed between the pair of third hinges 125, it is possible to reduce the size of hinge unit 114.

Next, description will be given of various modification examples of the digital camera 110 having an improvement in the rotational movement operability of the display 13 which is rotationally moved about the axis A integrally with the first support portion 121 and the second support portion 122 of the hinge unit 114, is rotationally moved about the axis C integrally with the second support portion 122, and is independently rotationally moved about the axis B.

In examples shown in FIG. 23, FIGS. 24A to 24C, a first rotational movement operating portion 140, a second rotational movement operating portion 141, and a third rotational movement operating portion 142 are included.

The first rotational movement operating portion 140 is provided to the second support portion 122 of the hinge unit 114, and is disposed away from the axis A on the long side 13 c located opposite to the long side 13 a of the display 13 along which the axis A extends and on the axis C biased toward the long side 13 c with respect to the axis A, or is disposed closer to the long side 13 c than the axis C. The first rotational movement operating portion 140 is provided in a state where a portion of the cover 16 of the display 13 that covers the hinge unit 114 is cut out and is exposed to the outer circumference of the display 13, and is constituted by a small piece-shaped protrusion capable of having a finger hooked thereon.

The second rotational movement operating portion 141 is also provided to the second support portion 122 of the hinge unit 114, and is disposed away from the axis C on the long side 13 a of the display 13 along which the axis A extends. The second rotational movement operating portion 141 is provided in a state where a portion of the cover 16 of the display 13 that covers the hinge unit 114 is cut out and is exposed to the outer circumference of the display 13, and is constituted by a small piece-shaped protrusion capable of having a finger hooked thereon.

The third rotational movement operating portion 142 is provided to the display 13, and is disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends. The third rotational movement operating portion 142 is also constituted by a small piece-shaped protrusion capable of having a finger hooked thereon.

In a case where the first rotational movement operating portion 140 is lifted up, the second support portion 122 of the hinge unit 114 provided with the first rotational movement operating portion 140 is rotationally moved about the axis A integrally with the first support portion 121, the display 13 supported by the second support portion 122 is also rotationally moved about the axis A integrally with the first support portion 121 and the second support portion 122. In a case where the second rotational movement operating portion 141 is lifted up, the second support portion 122 of the hinge unit 114 provided with the second rotational movement operating portion 141 is rotationally moved about the axis C, and the display 13 supported by the second support portion 122 is also rotationally moved about the axis C integrally with the second support portion 122. In a case where the third rotational movement operating portion 142 is lifted up, the display 13 provided with the third rotational movement operating portion 142 is independently rotationally moved about the axis B. Thereby, the display 13 is prevented from being erroneously operated in its rotational movement about each of the axis A, the axis C and the axis B, and thus it is possible to improve the rotational movement operability of the display 13.

Here, in the shown example in which the axis C biased toward the long side 13 c located opposite to the long side 13 a with respect to the axis A extending along the long side 13 a of the display 13 is provided to be spaced from the long side 13 c, the first rotational movement operating portion 140 is provided so as to be exposed to the lateral side of the long side 13 c, preferably, as shown in FIG. 25. Insofar as being exposed to the lateral side of the long side 13 c, the first rotational movement operating portion 140 may be provided so as to be exposed to the longitudinal central portion of the lateral side of the long side 13 c, may be provided so as to be exposed to the longitudinal end of each lateral side of the long side 13 c and the short side 13 b at the corner between the long side 13 c and the short side 13 b, or may be provided so as to be exposed to the longitudinal end of each lateral side of the long side 13 c and the short side 13 b at the corner between the long side 13 c and the short side 13 d.

The first rotational movement operating portion 140 provided so as to be exposed to the lateral side of the long side 13 c slidably moves on the bottom of the concave portion 17 of the main body 12 when the display 13 is rotationally moved about the axis C. Thereby, the edge E of the cover 16 constituting the lateral side of the long side 13 c slidably moves on the bottom of the concave portion 17 of the main body 12, and thus it is possible to prevent the display from being rotationally moved about the axis B due to friction against the bottom of the concave portion 17, and to further prevent the display 13 from being erroneously operated.

In the examples shown in FIGS. 23, and 24A to 24C, individual rotational movement operating portions are provided for the rotational movement of the display 13 about the axis A, the rotational movement of the display about the axis C, and the rotational movement of the display about the axis B, respectively, but examples shown in FIGS. 26, 27A and 27B show one rotational movement operating portion 150 which is simplified.

The rotational movement operating portion 150 is provided to the display 13, and is disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends.

The rotational movement operating portion 150 includes an engagement member 151 and a biasing member 152. The engagement member 151 is supported by the cover 16 of the display 13 so as to be movable between a locked position P1 engaged with the second support portion 122 of the hinge unit 114 and an unlocked position P2 released from the engagement with the second support portion 122. The direction of movement from the locked position P1 of the engagement member 51 the unlocked position P2 may be parallel to the axial directions of the axis A and the axis C, and may be parallel to the axial direction of the axis B, which has no particular limited thereon. The biasing member 152 biases the engagement member 151 toward the locked position P1.

The engagement member 151 is provided with a small piece-shaped protruding portion 153 which is exposed to the outer circumference of the display 13, and is capable of having a finger hooked thereon. By the operation of the protruding portion 153, the rotational movement operating portion 150 is lifted up, and the engagement member 151 is moved from the locked position P1 to the unlocked position P2.

In a case where the engagement member 151 is engaged with the second support portion 122 of the hinge unit 114 at the locked position P1, the display 13 is integrated with the second support portion 122. Since the second support portion 122 is not rotatable about the axis B with respect to the main body 12, the display 13 is rotatable only about the axis A and the axis C in a state where the engagement member 151 is engaged with the second support portion 122. The lateral side of one short side 13 b of the display 13 is exposed by the concave portion 17 which is open to one lateral side of the main body 12. For example, in a state where a finger is hooked on the exposed lateral side of the short side 13 b, the lateral side of the short side 13 b is lifted up, and the display 13 is rotationally moved about the axis A or the axis C.

In a state where the engagement member 151 is moved to the unlocked position P2 and is released from engagement with the second support portion 122, the display 13 is also rotatable about the axis B. In a case where the rotational movement operating portion 150 is lifted up in this state, the display 13 provided with the rotational movement operating portion 150 is independently rotationally moved about the axis B. Thereby, the display 13 is prevented from being erroneously operated in its rotational movement about each of the axis A, the axis C and the axis B, and thus it is possible to improve the rotational movement operability of the display 13.

In an example shown in FIG. 28, the initial torque of rotational movement of the display 13 about the axis B is made larger than the initial torque of rotational movement of the display 13 about the axis A and the initial torque of rotational movement of the display about the axis C.

In addition, the lateral side of one short side 13 b of the display 13 is exposed by the concave portion 17 which is open to one lateral side of the main body 12. In the present example, in a state where a finger is hooked on the exposed lateral side of the short side 13 b, the lateral side of the short side 13 b is lifted up, and the display 13 is rotationally moved in the direction of separating from the rear surface of the main body 12.

The revolution radius of an operation region about the axis B on the lateral side of the short side 13 b becomes longer than the revolution radius thereof about the axis A and the revolution radius thereof about the axis C. Consequently, the initial torque of rotational movement of the display 13 about the axis B is made relatively large, and thus an operation load during the rotational movement of the display 13 about the axis B can be made substantially equal to an operation load during the rotational movement of the display about the axis A, or can be made larger than an operation load during the rotational movement of the display about the axis A. Thereby, the display 13 is prevented from being carelessly rotationally moved about the axis B, and thus it is possible to improve the rotational movement operability of the display 13.

In the example shown in FIG. 28, a pair of magnets are included.

One magnet 160 is provided with the second support portion 122 of the hinge unit 114, and the other magnet 161 is provided with the display 13. The magnet 160 and the magnet 161 are disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends, and are disposed so that magnetic poles different from each other face each other.

The display 13 is adsorptively fixed to the second support portion 122 due to an attractive force which is generated between the magnet 160 and the magnet 161. Since the magnet 160 and magnet 161 are disposed away from the axis B on the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends, the initial torque of rotational movement of the display 13 about the axis B is increased due to the attractive force between magnet 160 and the magnet 161. A torque about the axis B based on the attractive force between the magnet 160 and the magnet 161 is appropriately adjusted depending on surface magnetic flux density and facing interval between the magnet 160 and magnet 161, and a distance between the magnets 160 and 161 and the axis B, and the initial torque of rotational movement of the display 13 about the axis B is set to be larger than the initial torque of rotational movement of the display about the axis A and the initial torque of rotational movement of the display about the axis C.

Preferably, the magnet 160 and the magnet 161 are provided adjacent to the short side 13 b located opposite to the short side 13 d of the display 13 along which the axis B extends so that the attractive force between the magnet 160 and the magnet 161 effectively acts as a torque about the axis B.

Further, when the display 13 rotationally moved about the axis B in the direction of separating from the rear surface of the main body 12 is rotationally moved again in a direction along the rear surface of the main body 12, the attractive force between the magnet 160 and the magnet 161 also acts so as to attract the display 13 to the rear surface of the main body 12. The display 13 rotationally moved up to the vicinity of the rear surface of the main body 12 is attracted to the rear surface of the main body 12 due to the attractive force between the magnet 160 and the magnet 161, and is automatically disposed at a proper position along the rear surface of the main body 12. Thereby, it is possible to further improve the rotational movement operability of the display 13.

Meanwhile, as shown in the example shown in FIG. 13, when the main body 12 is also provided with a magnet, and the display 13 rotationally moved about the axis A or the axis C in the direction of separating from the rear surface of the main body 12 is rotationally moved again in a direction along the rear surface of the main body 12 due an attractive force which is generated between the magnet 160 provided to the second support portion 122 of the hinge unit 114 and the magnet of the main body 12, the display 13 may be attracted to the rear surface of the main body 12. In this case, from the viewpoint that the initial torque of rotational movement of the display 13 about the axis B is made relatively large, the attractive force between the magnet 160 and the magnet of the main body 12 is set to be smaller than the attractive force between the magnet 160 and the magnet 161.

In addition, in the digital camera 110, the first hinge 123, the second hinge 124 and the third hinge 125 are also each provided with a click mechanism shown in FIGS. 14A and 14B, and the initial torque of rotational movement of the display 13 about the axis B can be made relatively large using the click mechanism.

In examples shown in FIGS. 29, 30A and 30B, the rotational movement of the display 13 about the axis A and the axis C is regulated in a state where the display 13 is rotationally moved about the axis B.

The concave portion 17 of the main body 12 having the display 13 received therein is provided with an engagement member 180 and a biasing member 181. The engagement member 180 is disposed on a revolution trajectory about the axis B of an edge E of the cover 16 constituting the lateral side of the short side 13 d of the display 13 along which the axis B extends, and is pressed by the edge E of the cover 16 when the display 13 disposed along the rear surface of the main body 12 is rotationally moved about the axis B in the direction of separating from the rear surface of the main body 12.

The engagement member 180 is supported by the main body 12 so as to be movable in a pressing direction between the locked position P1 at which the second support portion 122 is fixed to the main body 12 by engagement with the second support portion 122 of the hinge unit 14 and the unlocked position P2 released from the engagement with the second support portion 122. The biasing member 181 biases the engagement member 180 toward the unlocked position P2.

In a state where the engagement member 180 is released from the engagement with the second support portion 122 of the hinge unit 114 at the unlocked position P2, the display 13 is rotatable about each of the axis A and the axis B. In a case where the display 13 is rotationally moved about the axis B in this state, the engagement member 180 is moved to the locked position P1 due to pressure by the edge E of the cover 16 of the display 13, and engages with the second support portion 122 of the hinge unit 14. The second support portion 122 is fixed to the main body 12 by the engagement of the engagement member 180 with the second support portion 122, the second support portion 122 is prevented from being rotationally moved about the axis A and the axis C, and the display 13 is also prevented from being rotationally moved about the axis A and the axis C.

In this manner, in a case where the display 13 is rotationally moved about the axis B, the unnecessary rotational movement of the display 13 is eliminated by preventing the display 13 from being rotationally moved about the axis A and the axis C, and thus it is possible to improve the rotational movement operability of the display 13.
